Any other information on results incl. tables
Individual results
The test item was cooled down to -80 °C with a cooling rate of 1 K/min, -80 °C were kept for 60 min and 180 min, respectively, and afterwards the test item was heated up to 25 °C with a heating rate of 10 K/min. During heating up the measurements showed an exothermal effect (solidification) in the temperature range of (-80)- (-75 °C) and afterwards an endothermal effect (melting) in the temperature range of (-60)- (-45) °C. The solidification most likely took place at lower temperatures than the melting due to supercooling. The onset temperature was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline.
The results are summarized in the Table below:
| Ident No. | Test item / mg | Starting temp / °C | Final test temp / °C | Temp. range (endothermal) / °C | Onset (melting) /°C | Crucible | Observations after the measurement |
| 39049 | 15.13 | -80 | 25 | (-60) - (-45) | -55.05 | Aluminium with a hole | - |
| 39055 | 15.27 | -80 | 25 | (-60) - (-45) | -56.00 | Aluminium with a hole | - |
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
